Fleet Admiral Morrow: You've all done a remarkable service under the most difficult conditions. You'll be receiving Starfleet's highest commendations. And more importantly...extended shore leave. That is, all but you, Mr. Scott. They need your wisdom on the new Excelsior. Report there tomorrow as Captain of Engineering.

Montgomery Scott: With all appreciation, sir, I prefer to supervise the refit of Enterprise.

Fleet Admiral Morrow: In your absence, Genesis has become a galactic controversy. Until the Federation Council makes policy, you are all under orders not to discuss with anyone your knowledge of Genesis. Consider it a quarantined planet...and a forbidden subject.

Fleet Admiral Morrow: Out of the question, my friend. The Council has ordered that no one but the science team goes to Genesis! Jim, your life and your career stand for rationality, not for intellectual chaos! Keep up this emotional behavior, and you'll lose everything! You'll destroy yourself! Do you understand me, Jim?

Montgomery Scott: Aye, sir. The more they overthink the plumbing, the easier it is to stop up the drain. [hands McCoy a fistful of computer chips] Here, Doctor, souvenirs from one surgeon to another. I took them out of her main transwarp computer drive.

James T. Kirk: That's what you get for missing staff meetings, Doctor. Gentlemen, your work today has been outstanding. I intend to recommend you all for promotion...in whatever fleet we end up serving. Best speed to Genesis.

[One of Kruge's gunners has defied a direct order to disable the engines of the USS Grissom by destroying the ship with everyone inside except Saavik, Spock and David Marcus.]

James T. Kirk: With some of them on the planet. I swear to you, we're not finished yet. Bones, you and Sulu to the transporter room. The rest of you with me, we have a job to do. [to Kruge] Commander of Klingon vessel...prepare to board this ship on my next signal.

[Leonard, seated before Spock, who's lying unconscious on a bed in the sickbay of the Klingon Bird of Prey en route to Vulcan]

Leonard McCoy: Spock! For God sakes, talk to me! You stuck this damn thing in my head, remember? Remember? Now tell me what to do with it. Help me. [McCoy sits up straight: his face visibly changing from an air of urgency to one of concern.] I'm going to tell you something that I...never thought I'd ever hear myself say. But it seems I've...missed you, and I don't know if I could...stand to lose you again.

T'Lar: Sarek! Child of Skon! Child of Solkar! The body of your son breathes still. What is your wish?

T'Lar: McCoy, son of David. Since thou art human, we cannot expect thee understand fully what Sarek has requested. Spock’s body lives. With your approval, we shall use all our powers to return to his body that which you possess. But McCoy, you must now be warned. The danger to thyself is as grave as the danger to Spock. You must make the choice.
